PO RTABLE STEAM=AUGER.

SPECIFICATION forming part of Letters Patent No. 271,480, dated January 30, 1823,

' Application filed April 26, 1882. (No model.)

To all whom it may concern Be it known that 1, WILLIAM F. LEACH, of St. Clair, in the county of St. Clair and State of Michigan, have invented new and useful Improvements in Portable Steam-Augers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

The nature of this invention relates to certain new and useful improvements in the construction of portable steam-angers, and is especially designed as an improvement upon a device of that character patented to me July The invention consists in the peculiar combination of mechanism by means of Which the speed of the auger is regulated, and also in the means provided for handling the device, and in the combination and operation of the various parts, as more fully hereinafter described.

In the accompanying drawings, wherein my invention is shown in elevation in Figurel and in an end view in Fig. 2, A represents the shaft of a rotary engine, 13, which latter may be of any of the known constructions. Sleeved upon the stuffing or journal box of this shaft is the huh I), adjust-ably secured in place by the. set-screw'a upon the shaft-beariugf, rigid with and projecting from the main frame of the engine, and provided with an arm, I), which carries the counter-shaft E in such manner as to allow the same to revolve.

Upon the shaft A is adjustably secuied, by any of the known means, the pinion G, designed to communicate motion to the shaft E through the pinion F, which is also adjustably secured upon the shaft E, in the end of which is provided a socket, c, to receive the shaft of an auger, which, when inserted,is secured therein by the set-screws (Z. By this arrangement, the speed of the engine being known, as well as the required speed of the auger, which latter it is desired to change with various descriptions of work, the changing of the pinions upon the shaft and counter-shaft to correspond will enable the operator to increase or diminish the speed of his auger-shaft without changing the speed of the engineshaft. The opposite end of this shaft runs in a box or bearing, upon which there is sleeved a short length of gaspipe, h, secured by setscrews 1'. The free end of this gas-pipe terminates in a T- head, K, secured to said gas-pipe by means of a set-screw, it; or any other convenient form of handle may be attached for the purpose of allowing the operator or operators to more readily handle the device in any position where it may be necessary to use the auger.

The manner of using my invention is as follows: Thespeed at which the auger is to be driven having been regulated by the relative size of gearsO F, the operatoradjusts the collar D and arm I) to the desired position by the setscrews 0, and holds the device in the desired position by the handle K. Steam then being admitted into the engine, the shaft A turns, and, by means of the gears O F, rotates the counter-shaft E in the opposite direction, and thereby imparts motion to anauger held in the socket at the end of the counter-shaft.

Having described myii1vention,whatI claim as new, and desire to secure by Letters Patent, 1s-

1. The combination, with a rotary engine and the shaft thereof, of a movable bearing constructed to be adjusted around said shaft, a second shaft adapted to carry an auger and revolving in said adj ustahle bearing, and gearwheels transferring the-motion of the shalt of the engine to the shaft revolving in the adjustable bearing, substantially as and for the purpose specified.

2. The combination, with a rotary engine and the journal-box f thereof, of the hub D, carryingthe arm I), constructed to be adjusted around said box, and a second shaft adapted to carry an auger and revolving in said adjustable arm, both shafts being provided with gear-wheels meshing with each other, all constructed and arranged substantially as and for the purpose specified.
